Hello čaute i had problem with my pc,so i bought new one with new HW and SSD,but i have kept my old hdd. I would like to copy my profile from E:\Users\user\AppData\Roaming\Mozilla\Firefox\Profiles to C:\Users\user\AppData\Roaming\Mozilla\Firefox\Profiles I did ,it is almost 1,2 GB file. After copy i tried to open new mozilla that is on new ssd,but it gave me this error message: User profile firefox app cannot be loeaded. Probably profile is missing or it is unavailable. Could be because i have dowloaded older version from march? What can i do. It is very important for me to have all my old bookmarks and history. I tried first to import my bookmars which was succesful, but i would also like to have my old webhistory and old theme. Also i am not sure but i found somehting about places.sqlite , it is my old history of browsing? Can i put it into new profile somehow? Please prosim help pomozte. Anything

Please explain the problem in detail. What happens? What is/are the exact error message(s) ?


Do you still have the old hard drive?


Let's start from the beginning.

Step 1 Use these links to create a new profile. Use this new profile as is.

Step 2 When you are ready, we can start moving parts of your old data and Copy it to the new profile.


First; open your file browser to the New profile;

Type about:support<enter> in the address bar.

Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.

Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder

Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.


Second, open another file browser to the Old profile.


Warning ! ! Only Copy the files you are told. We will avoid anything that might cause problems. Here is the list of files;

cookies: cookies.sqlite Do not bother. Cookies will be created when you return to the website. However, you will have to log in everywhere. And you may lose any settings that websites store on your computer.

extensions(add-ons, themes): it would be better to download them fresh. If you need to remember what add-ons you had, open the extensions sub-folder and look at the .xpi files


logins.json and key3.db [v58+]key4.db : These are the password files. Copy Both !

persdict.dat : custom dictionary - words you added to the dictionary

mimeTypes.rdf [v55+]handlers.json : What to do with what type of file.

places.sqlite : History and Bookmarks.

prefs.js : Your settings. Note: If you were having problems, this could be contaminated.

cert8.db [v58+]cert9.db and possibly cert_override.txt : Stores all your security certificate settings and any SSL certificates you have imported into Firefox. If removed, the cert8.db, cert9.db file will be replaced.

search.json.mozlz4 : file stores the user-installed search engines that are available in the Firefox v47+

search.sqlite file and searchplugins folder store the search engines that are available in the Firefox Search bar before Firefox v47


Copy these files from the old to the new. You may get a message that the files already exist. Choose to over-write for each file.

Hi. Please explain the problem in detail. I want copy my old profile from hdd to new mozilla path in the new ssd.

What happens? What is/are the exact error message(s) ? The error message is in my language but i will translate: Missing user account. User acc for firefox app couldnt be loaded. Probably is missing or is it unavailable.


Do you still have the old hard drive? Ofc thats what i am talking about, i have both drives connected and i can see it in MY PC Or tried copy old files into new mozilla path. But i will try your advice tommorow and let you know what happens.
